With the Meta-analysis method, the clinical efficacy of acupuncture and other regular methods for aphasia was evaluated, and the acupoints selection for aphasia was explored. The acupuncture literature of clinical randomized control trials for aphasia published in CNKI, WANFANG, VIP and CBM database was searched; the statistical analysis of clinical efficacy of acupuncture and other regular methods for aphasia was performed by using software Revman 5. 2 provided by Cochrane library. A file of Microsoft Excel was established to perform the analysis of acupoints selection based on frequency analysis method, so as to summarize the characteristics and rules. Totally 385 articles were searched, and 37 articles those met the inclusive criteria was included, involving 1,260 patients in the acupuncture group and 1 238 patients in the control group. The Meta-analysis results showed OR = 3.82, 95% Cl [3.01, 4.85]; rhombus was located on the right side and the funnel plot was nearly symmetry, indicating the treatment effect of the acupuncture group for aphasia was superior to the control group (Z = 11.04, P < 0.000 01). The frequency-analysis results showed that the frequency of acupoints from top to bottom was Lian-quan (CV 23), Tongli (HT 5), Yamen (GV 15), Jinjin (EX-HN 12), Yuye (EX-HN 13), Baihui (GV 20), Yuyan II, Yuyan I and Yuyan III. The frequency of meridians from top to bottom was the governor vessel, extra channels, conception vessel, heart meridian and large intestine meridian. It is concluded that the clinical efficacy of acupuncture combined with speech rehabilitation training and medication treatment for aphasia is superior to that of speech rehabilitation training and medication treatment alone. The clinical treatment for aphasia focuses on its local effect; the main acupoints are in the head and face, and the meridians are governor vessel, extra channels and conception vessel.

Objective To investigate the situation of ALT-single-unqualified blood donors and the ALT test when they donated again.Methods There were 3 784 cases of ALT-single-unqualified blood donors from March 2009 to February 2010 enrolled in the study.Investigations were carried out to know the previous situation of blood donation.A 3-year tracking survey on those people was carried out,and the data was recorded and analyzed.Results The ALT-single-unqualified blood donors who participated in blood donation for the first time accounted for 58.14% (2 201/3 748).The 3-year follow-up showed that the returned blood donors accounted for 33.62% (1 272/3 784);1-year return accounted for 46.62%(593/1 272)which was the most;ALT-qualified donors accounted for 65.72%(836/1 272)of the retured donors.with the increase of the times of blood donation,the qualified rate of blood ALT increased.Conclusion More than half of the ALT-single-unqualified blood donors returned.There was a large proportion of returning donors participated in blood donation more than onece,and the qualification rate of ALT increased with the increase of do-nation times.In order to reduce the unqualified rate of ALT test,we should strengthen the propaganda and fixed blood donation team construction.

Objective To explore the effect of comorbidities on the surgical outcomes of elderly patients with hip fracture. Methods The Age,gender,weight,type of fracture,preoperative comorbidities and surgical outcomes of 117 patients aged 80 yr or over who undergoing hip fracture surgery in our hospital were recorded. Patients were divided into rehabilitation group and postoperative in-hospital death group ac-cording to surgical outcomes. The potential predictors of postoperative in-hospital death were identified by univariate model and were then entered into multiple Logistic regression analysis. Results Twenty three patients(19. 7%)had no comorbidity,94 patients(80. 3%)had one or more comorbidities. Ten patients(8. 5%)died in hospital after the operation. Predictors of postoperative in-hospital death were preoperative respiratory diseases and three or more comorbidities. Conclusion Surgical outcomes of elderly patients with hip fracture may be predicted by analysing preoperative comorbidities. Preoperative preparations must be sufficient in order to ensure successful operation.

Objective To evaluate the surgical outcomes in octogenarians and older of gastric cancer and to identify the reasonable therapy for these patients.Methods From Jan 2000 to Dec 2010,the clinicopathological data of 533 patients with gastric cancer undergoing gastrectomy were analyzed retrospectively.We conducted comparative analysis for the differences in clinicopathological characteristics and prognosis between 80 years and older (≥80 y,n =75) and younger (＜ 80 y,n =458).Results There were significant differences in comorbidities,anemia and histological type between the two groups.There was no significant difference in operative morbidity and mortality between the two groups.The 5-year survival rate for octogenarians was lower (21.1％) than nonoctogenarians (32.8％),but with no significant difference.TNM stage was the only independent prognostic factor for gastric cancer in octogenarians.Conclusions Older gastric cancer patients have comparative postoporative complication rate and survival with younger patients.

Objective To evaluate the impact of preoperative prognostic nutritional index (PNI) on surgical outcomes and long-term survival of elderly patients with gastric cancer.Methods From Jan 2007 to Dec 2012,the clinicopathological data of 165 elderly patients (age ＞ 65 years old) with gastric cancer undergoing radical gastrectomy in the Second Hospital of Tianjin Medical University were analyzed retrospectively.PNI value was calculated by serum albumin (g/L) + 5 × lymphocyte count (× 109/L).The receiver operating characteristic (ROC) curve and Youden index was used to determine the cut-off value of PNI.Patients were then divided into low PNI group and high PNI group based on the cut-off value.The two groups were compared according to clinicopathological characteristics,postoperative complication and longterm survival.Results The mean PNI value was 46.1-± 5.3,When the PN1 was 46.4,the Youden index was maximal,with a sensitivity of 78％ and specificity of 59％.There were 79 patients in the low PNI group and 86 patients in high PNI group.No significant correlations between PNI and gender,age,BMI,pathological type,tumor diameter,extranodal metastasis and postoperative morbidity were observed.There were significant difference in the depth of invasion (x2 =6.732,P =0.009),N stage(x2 =13.191,P =0.004),TNM stage(x2 =12.137,P =0.000) and postoperative hospital stay (t =4.595,P =0.000).By Kaplan-Meier method,PNI (P =0.000),depth of invasion (P =0.002),N stage (P =0.000),TNM stage(P =0.000) and extranodal metastasis (P =0.031) had significant impacts on overall survival.PNI (P =0.016)and N stage (P =0.018) were independent factors for predicting overall survival rate.Conclusions PNI helps in evaluating preoperative nutritional status and postoperative prognosis for elderly patients with gastric cancer.

Objective: To explore the clinical value of non-invasive monitoring of cerebral hemodynamics for evaluating intracranial pressure (ICP) and cerebral perfusion pressure (CPP) in patients with moderate to severe traumatic brain injury (TBI). Methods: Transcranial Doppler (TCD) was employed to detect the hemodynamics of bilateral middle cerebral arteries, including systolic blood fl ow velocity (Vp), diastolic blood fl ow velocity (Vd), average fl ow velocity (Vm), pulsatility index (PI) and resistance index (RI) in 52 patients with moderate to severe TBI. At the same time, the CPP, ICP and mean arterial blood pressure (MABP) were monitored. The correlations between hemodynamics and MABP, ICP as well as CPP were analyzed. Results: The PI and RI were positively related to the ICP (r=0.881, P<0.0001; r=0.789, P<0.0001). Multiple stepwise regression analysis showed PI was closely associated with ICP (ICP=-8.593+24.295PI; t=13.216, P<0.0001) and signifi cant correlation was also found between CPP and PI as well as MABP (CPP=15.596-22.886PI+0.910MABP; F= 76.597, P<0.0001). Conclusion: Non-invasive monitoring of cerebral hemodynamics by TCD can refl ect the real time changes in the ICP and CPP and may be used as an effective tool to monitor the ICP and CPP. This method is non-invasive, safe, cheap, repeatable and applicable in clinical practice.

Obje:ctive To establish an optimized method to isolate, culture and identify human umbilical cord mesenchymal stem cells (hUCMSCs) in vitro and induce their osteogenic and adipogenic differentiation. Methods The hUCMSCs were isolated from human umbilical cord by digestion with collagenase. After serial subcultivation in vitro, the stem cells were passaged. Morphologic appearance of hUCMSCs was observed under an optical microscope and atomic force microscope. The proliferation rate was measured by MTT assay. Cell cycle and surface antigens were measured by flow cytometry. The osteogenic and adipogenic differentiation was tested and evaluated by specific staining methods. Results The isolation of hUCMSCs by digestion with collagenase was efficient. After seeded for 24 hours, the adherent cells showed spindle shape and fibroblast cell-like shape and the size of hUCMSCs was homogeneous. The similar growth curves of passage 3 and 7 exhibited a great potential for proliferation. Flow cytometry analysis revealed that CD29, CD44 and CD105 were highly expressed on the surface of passages 3 cells, but the expression was negative for CD34, CD45 and HLA-DR. After culture in inducing medium, the cells were successfully induced into osteogenic and adipogenic lineages. These cells were highly positive for alkaline phosphate staining and also showed mineralization presented with von kossa staining after 4 weeks' culture induction of osteogenic differentiation. Furthermore, liquid vacuoles were detected by oil red O staining after 3 weeks' culture induction of adipogenic differentiation. Conclusion An in vitro method for isolation and purification of hUCMSCs from human umbilical cord has been established. The cultured cells were composed of only undifferentiated cells and their biological properties were stable. The hUCMSCs are expected to be a new type of stem cells of tissue engineering.

To explore the spatial distribution mechanism of Japanese encephalitis virus (JEV), PhyML v3.0 was used to build phylogenetic tree using JEV sequences in the dataset. PAUP v4.0 and Migrapyhla softz ware were then used to analyze the migration events. The results showed that a total of 95 migration events were observed during the dispersal of JEV throughout Asia. Further analysis revealed that Thailand, and several Chinese provinces (including Shandong, Shanghai, Sichuan and Yunnan), were the main migration sources of JEV. JEV spread from these migration sources as follows: from Thailand to Australia, Cambodia, Tibet and India; from Shanghai to eastern coastal Asian regions and Yunnan; from Shandong to Korea, Zhejiang, Hubei, Shanxi and Liaoning; from Sichuan mainly to inland regions of China, as well as Vietnam and Japan; and from Yunnan to Zhejiang. This study indicated that frequent migration events occurred during the dispersal of JEV in the Asia and Pacific regions, and that Thailand, Shandong, Shanghai, Sichuan and Yunnan were the sources of JEV dispersal.
